Media centre out of control? Now one of the units is on the fritz and you're tugging on cords to figure out which one to unplug. Save yourself future headaches and wrap labels (I simply use file folder labels) around the ends of cords plugged into a power bar, and label the item they’re attached to. Electronics and office supply stores sell cord wrappers designed for this as well. Obviously it is best to label during the installation process, but if it's too late for that, be sure to get to it before you're caught off-guard.
